CHARLES A. PERFECT, OF SUNBURY, OHIO.

STORAGE STRUCTURE.

Application filed April 24, 1911.

To all whom it may concern Be it known that I, CHARLES A. PERFECT, a citizen of the United States, residing at Sunbury, in the county of Delaware and State of Ohio, have invented a certain new and useful Improvement in Storage Structures, of which the following is a specification.

The object of this invention is to provide an improved construction of wall especially for use in the erection of silos.

The invention is embodied in the details of construction herein shown and described and then pointed out in the claims.

' In the accompanying drawing Figure 1 is a horizontal section on the line 00-20 Fig. 2. Fig. 2 is an elevation of a portion of a silo looking at the vertical opening thereto.

Fig. 3 is a perspective view illustrating the form of block employed in the construction of the silo. Fig. 4 is a detail showing the details of the means for tying the wall and the ladder together at the vertical opening. Fig. 5 is a horizontal section on the line y z Fig. 4 looking down.

As shown in the views the blocks 10 (preferably of cement or concrete) are of curved parallelopiped form and provided in their upper surfaces with a deep longitudinal groove 11 inclined toward the concave side side of the block or toward the vertical axis of the silo. The bottom of this groove lies in a center line of the block so as to provide between the wire hereinafter referred to and the inner surface of the wall a thickness of half the block. The lower side of the block is provided with a longitudinal groove 12 of rhomboidal form in cross section and is made on a line to match or lie over the grooves of the blocks upon which they are superposed in laying the courses.

13 designates a stout wire or cable that is laid around in the bottom of the grooves 11 in each course. The two ends of each of these wires or cables are each provided with a threaded eye bolt 14:.

The ladder includes upright or side pieces of pipe 15 sections of which are connected by threaded internalunions 16 preferably with right and left hand threads and so as not to leave considerable projections on the outside of the pipe. The rungs of the ladder are formed of bars 17 having saddles 18 at their ends to fit against the pipes 15. The pipes 15 and lower portions of the saddles Specification of Letters Patent.

18 are perforated horizontally to receive a bolt 19 with a nut 20 to preliminarily secure the rung to the ladder.

The terminal blocks on each side of the vertical opening to the silo are grooved to receive the upright portions 15 of the ladder as seen in Fig. 1. When a course of blocks has been laid the eye bolts 14: of the wire or cable 13 are passed through a horizontal perforation in the pipe and the upper portion of the saddle and the wire or cable drawn up tight by means of a threaded nut 21. The ladder with its rungs is thus made a part of the metallic structure binding the cement or concrete wall tightly together. The particular form of the groove 11 causes the wire, when tightened to seek the bottom of the groove and prevents the wire from slipping upward after it has been secured and the fact that the bottom lies on a line deeply within the block and in a central plane insures ample material to take the strain of the wire when tightened.

Before one course of blocks is laid on another the inclined groove 11 is filled heaping full with mortar or cement or to such an extent that an excess will be left to fill the groove 12 in the block being put on as seen at 22in Fig. 3 so that when such mortar or cement hardens it will aid in binding the courses horizontally together and also preent seepage of moisture through the wall at the planes between the courses. As usual in silos of this kind the vertical opening or doorway is closed as the silo is charged with ensilage by means of wooden blocks as seen at 23 in Fig. 1.

I am aware that the art to which this invention relates is much developed and that the present invention is not the first to propose a wall of cement or concrete held together by a metallic frame and I therefore do not make broad claims to such.

lVhat I claim is:

1. A circular storage structure wall having a vertical opening from top to bottom made up of blocks having their upper sides provided longitudinally with deep wire or cable-receiving grooves said grooves being inclined toward the vertical aXis of the storage structure and having their bottoms lying in a line approximately midway between the inner and outer sides of the blocks combined with continuous wires or cables in such grooves and means in the doorway connecting the ends of said wires or cables to independently hold them in a state of tension substantially as described.

2. A circular storage structure wall made 'up of blocks, said structure having a vertical doorway in its side, saidblocks having their upper sides provided longitudinally with wire or cable-receiving grooves, combined with continuous wires or cables in such grooves, and a ladder erected in said vertical doorway comprising vertical side pieces of pipe and rungs having cross saddles at their ends to fit against said side pieces, bolts and nuts connecting said saddles to said pipes, threaded eye bolts provided with adjustable nuts thereon connecting the opposite ends of said wires or cables to said pipes and saddles whereby each of the cables may be independently tightened, and doorway closing members set in said doorway beyond said rungs to permit the use of said rungs when the doorway is closed.
